Cisco Jabber vs Slack: Which is best for you?

Jabber is available on both PCs and mobile devices, allowing for continuous communication even when away from the office.

Also, I don't like that much the fact that you cannot see the previous chat maybe in other days since the data and the message are not saved.

It allows for sharing of documents, links, doing a hurdle, and screen sharing and all those other essential things important in a semi professional environment.

I hate it when I receive a call and I don't have my earphones connected. If I answer the call directly, I find that many times the earphones are not recognized, and usually I need to restart Slack to make my earphones recognizable. When you have an important call, that sucks.
